Answer:
I believe its B, But I am unsure since I haven't done geometry in a couple years.
The answer is 170 because the number next to it is not 5 or more
To make that a perfect square polynomial,
follow these steps:
1. Take the co-efficient of x term: here -16
2. Divide it by 2: -16/2 = -8
3. Square it. : (-8)^2 = 64
Thats it! 64 is the missing term you need :)
Yes, it would only be irrational if the numbers had no end, (not repeating like .6666666…)
decimals that end, or repeat the same pattern are rational numbers.
